Claims:WE CLAIM
1. A robotic apparatus for building a multidimensional object, the apparatus comprising:
an extruder unit configured to receive a plurality of materials to build the multidimensional object, the extruder unit comprising:
a plurality of nozzles comprising a plurality of changeable orifices to extrude a plurality of pre-defined patterns of the plurality of materials; and
a spring steel valve configured to isolate cross flow contamination of the plurality of materials to allow a positive extrusion of the plurality of materials, wherein the spring steel valve restricts the backflow of the plurality of materials, wherein the extruder unit is configured to move concurrently in a forward direction and a reverse direction while extruding the plurality of materials;
a support structure comprising:
a plurality of sides to form an outer surface of the support structure; and
a plurality of rails integrated with the plurality of sides to form a multidimensional path for the extruder unit;
a plurality of motor units electrically configured with the plurality of the rails to control an elevation of the extruder unit, wherein the plurality of motor units is configured to control the movement of the extruder unit; and
a modeling platform to provide a build surface to support the multidimensional object, wherein the modeling platform is rotatable to a pre-defined degree, and wherein the modeling platform is configured to move in a forward direction and a reverse direction.
2. The apparatus according to claim 1, wherein the extruder unit comprises: a thermistor to measure a temperature of the received plurality of materials; and a cooling fluid to control the temperature of each of the plurality of nozzles.
3. The apparatus according to claim 1, wherein the plurality of changeable orifices has a pre-defined output geometry dies.
4. The apparatus according to claim 1, wherein the plurality of motor units configured with the extruder unit utilizes at least one of a peristaltic pump and a solid filament drive for changing the plurality of changeable orifices.
5. The apparatus according to claim 1, wherein the modeling platform comprises a centrifugal internal pump for extruding the plurality of materials.
6. The apparatus according to claim 1, wherein the modeling platform is configured to rotate 120 degrees, and wherein the modeling platform is configured to change the extrusion dies.
7. The apparatus according to claim 1, further comprises a cooling mechanism placed in vicinity of the extruder unit to decrease temperature of the multidimensional object.
